DERAILING DEVICE;

I Speeific ation of Letters Patent. 1

To all zohomitmay aim-em.-

Be itknown that I, GEORGE W. NIBBE, a

citizen of the United States, anda resident of Chicago, in the countyof'Cook and State of Illinois, have inventedfcertain new and. usefulImprovements in DerailingDevic'es;

and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.- l f This invention relates to an improvement 'inderailing devices and consists of the matters hereinafter described andmore particularly'pointed out in the appended claims.

, The railroad rails used by difierent roads, and even those used by thesame roadon different branches and in yards may vary widely in weightand the different weights of rail vary in height, that is to say, in thedistance from the top of the ball of the rail to the base flange whichrests. onthe tie.

Derailing devices, as heretofore constructed, have been such that it hasbeen necessary for each railroad'to have a supply of derailing devicesfor each weight of rail used inits system. This. is annoying .and' ex--.pensive and the object of the present invention is to provide aderailing device capable of such adjustment that it may be applied "torails of any of the several weights between the maximum and minimumlimits now employed by railroads;

In the drawings, Figure 1 is a view representing in perspective one ofmy improved derailing devices applied to a rail, as it appears whenlooked at from a point beyond the outer side of the rail., Fig. 2 is aview in side elevation of the derailing device with the lugs or ears, towhich the derailing member is hinged, shownin vertical section. Fig. 3is a view representing avertical section through the derailing device ina plane indicated by the line 33 of Fig. 2.-

Fig.4 is a view representing a vertical section through the derailingdevice in a plane indicated by the lineH of Fig. 2. Fig. 5 is a viewsimilar to Fig.' 3, except that the parts of the derailing deviceare-shown ad- :justed in a differentrelation in order to accommodate arail of a different height.

Fig. 6 is a perspectiveview of the shaft upon which the movable partofuthe derail- 'ing device is rotatablym'ounted. 5

Referring now to that embodiment of my Patented Sept. 1, {19 14.Application filed November 10, 19 13. 1 Serial No."80j0,026.. r r qinvention illustrated in the drawings, 10 indicates'. a rail attached toand supported.

upon ties l1-inthe usual manner. The dera ling .device'is'applied to therail at a point between two ties where a channel 12 below the rail baseis formed in the ballast or 'roadbed to provide space for the parts ofthe device whichare located of the rail base.

below thelevel F My improved derailing device includes the usualderailing blocklS, whichis carried by a rock arm 14; a supporting andattaching member 15 by means of which the device is attached to the railand by which the rockfarm 14: is rotatively carried; and

an operating link 16 which extends transversely under the rail in theusual manner. The derailing block'13 is of any familiar or convenientconstruction and has a rail tread 17 which isinclineddownwardly so as ato merge atone end: into the top surface of.-

the rail in order :to guide the tread of the wheel to thetop of theblock and hasan upright flange 18 inclined diagonally across said tread:from its inner to its outer edge so constructed that it will catch thewheel flange and force said wheel as it ridesupon said block to travelin a diagonal'direction across the block from its inner edge to itsouter edgecin such manner as to derail the wheel. The formation of saidblock is of no interest in the present invention as it maybe "of anyapproved or preferred construction known to those familiar with theart,.so that a further description of the same is unnecessary.

The attaching and supporting member l5 has an upright flange 19 adaptedfor engagement with the outerface of the web of the rail and providedwith apertures for bolts by means of which it may beIattached to therail. Said supporting member also has a base 'flange 21 for engagementwith the top face ofthe rail base flange. Said supporting memberisvprovidedowith longitudinally, spaced lugs 22 in'which is carried anon-rotative shaft 23"extendin'g parallel to the rail 10 andconstituting the member upon'which the rock :arm 14: connected to thederailing block13'is hinged. Each of said lugs 22 has a verticallyelongated slot '24: of a width substantially equal to the diameter ofthe shaft 23. Thevertical sides of said slot are "provided vwithvertically spaced notches or keyways, 25 which are adapted to receiveoppositely placed keys 26, 26 fixed to the shaft 23. There are two pairsof such keys fixed to the shaft, one 1321.11 being placed near one endand one pair In order to provide vertical adjustment.

of the shaft 23 at points as closely spaced together as possible withoutunduly diminishing the thickness of the keys 26, 26 and the width of thegrooves or keyways 25 in which they are secured, I prefer to place thekeys on opposite sides of aplane through a diameter of the shaft 23 andto arrangethe keyways 25 on the opposite sides of the slots 24 instaggered vertical relation. Manifestly, the shaft may be adjusted dis-.tances equal to half the vertical distance between the keyway notchesin the grooves by. reversing the shaft end for end, thus bringing thekeys on one side of the shaft into engagement withone of the keywayswhich was engaged in the first instance, and bringing the keys on theother side of the shaft into engagement with the keyways next belowthose with which the shaft was engaged in the first instance. The arm 1%is provided with a bearing aperture 28 to re-- ceive the shaft 28 andsaid bearing aperture has on each side notches. 29, so that the shaftwith its keys may be passed through the aperture in the arm 14 inassembling the device no matter which way the keys are disposed.

30 indicates horizontally spaced lugs on the arm 14 which projectdownwardly be low the level of the shaft 23, and which are provided withapertures for the reception of a pivot bolt or nut 31 by means of whichthe link 16 is operatively connected to said arm 14. The longitudinalmovement of the link 16, produced by suitable mechanism placed on theoutside of the rail opposite the rail 10, operates to swing the arm 14so as to apply or remove the block 13 to or from the rail as desired, inthe usual manner.

In order to lock the derailing device in position, one of the lugs 22 isprovided with a flange 34 having a vertically elongated slot 35 and thearm 14L is provided with a similar flange 36 placed adjacent to theflange 34 and having alike vertically elongated. slot 37. The hasp of alock passed through said two slots will apparently lock the parts insuch position as to rigidly hold the derailing block on the rail.

l/Vhile in describing my invention, I have referred to certain detailsof mechanical construction and arrangement, it is to be understood thatthe invention is in no way limited thereto except as pointed out in theappended claims.

I claim as myinvention:
